If this service (or any other) is being discussed on this forum, then there is no reason why members may not ask questions and answers about precisely what the service is, how much it costs and where the money goes.
After all this time, I still haven't seen transparent answers to the key questions about the business model here, nor have I seen a comparison with other options that may be available.
But the best I can determine so far is that I have heard that ARL sometimes offers their tests for around $50, based on which it seems reasonable to imagine that the rate charged to a consultant customer might be something similar. If that were the case then a $200 charge for a test with analysis would value Christine's analysis and report at $150 a pop. Significant reductions in price could also be yielding a profit, and there is no guarantee that 'at cost' really means what it says if you don't know what the true cost of the tests is. There also seems to be no guarantee that Christine's analysis really is either (a) individual, (b) different from the analysis by the lab themselves, or (c) reliable and meaningful.
It would seem to be a quite straightforward model for customers to order the test directly from the provider and forward the results to any practitioner who wanted to offer additional interpretation to that provided by the lab. Any customer should be demanding to see the direct results from the lab. If you don't ever see those results, sent directly from the lab, you don't even have a guarantee that a lab test has actually been performed; you could have just been given a standard or random interpretation. Even with the lab itself, only independent oversight and accreditation can assure you that tests really are being performed. Without these guarantees, any service like this is wide open to abuse and exploitation.
I would like to see on this thread some comparative analysis of hair mineral testing services: the prices of various services and precisely what they provide. It is not unreasonable for any customer or potential customer of these services to ask these questions.
